在P2P無線網路環境中進行串流媒體的分享，如何讓節點在無線網路環境中有效地去取得所需要的資料將是一個值得探討的研究。目前許多的研究提出在P2P無線環境中進行串流媒體的分享機制與排程方法，大部分講述的都是如何有效地利用網路頻寬，採取貪婪的方法來滿足將資料快速到達Client為首要目標。然而當節點數量增加以及進行交換的連線與傳輸在逐漸遞增之下，容易造成整個網路傳輸負荷過大的情況發生。以串流方式來分享媒體資料之特性為當Segment只需要在播放時間之前傳輸完成即可，另外過早將Segment擷取下來儲存，是形成緩衝區空間一種不必要的浪費。因此本篇論文我們將提出了一個新的排程方法，使得在擁有大量節點的P2P無線網路中，除了可以保持網路傳輸的品質並且使得在播放之前可以確實地接收到資料；我們由模擬結果可以得知，此排程確實可以降低整個網路資源被浪費情形，並且不會造成多餘的封包被丟棄的情況發生。

At present, many studies in the wireless environment for P2P streaming media-sharing mechanisms and scheduling methods, most are about how the effective use of network bandwidth, the greedy method to take the information to meet the objective of the rapid arrival of Client. When the increase in the number of nodes as well as upload / download of the increase in the number, it is easy to load the entire network from happening too much, too early to Segment at the same time to download and storage, the buffer zone is a waste of space. This paper presents a new scheduling method, a large number of nodes in a P2P wireless network, in addition to maintain the quality of network transmission and make the player can confirm that prior to the information received. Can be learned through the simulation results, the scheduler can indeed reduce the network where resources are wasted, and will not cause extra packet being discarded happen.
